Dong is a lecturer in bioinformatics who contributes to various research activities in the College while leading his own research. Dong's research interests focus on understanding the molecular mechanisms of host-pathogen interactions using high-resolution approaches coupled to bioinformatics. He is interested in 'big data' analysis, where datasets generated from multiple omics platforms are integrated for system modelling.

Dong obtained his Biological Science degree from Shandong University in China followed by MSc by research training in the University of Edinburgh. He has then enrolled a PhD program in the School of Veterinary Science, University of Liverpool on infection biology to characterise the proteomics of Toxoplasma gondii.

After completing his PhD, Dong has led and involved in various bioinformatics and wet lab based projects such as developing informatics tools for mass spectrometry data analysis, genome annotation improvements and characterising molecular mechanisms of host-pathogen interactions in several important veterinary and human infectious diseases, ranging from protozoan parasites, bacteria, worms and viruses.

In 2017, he was appointed to a lectureship at the Royal Veterinary College in the University of London, where he continues his research interests in understanding the molecular mechanisms of host-pathogen interactions using multi-omics approaches coupled to bioinformatics and contributes to the RVC Quantitative Biology Resource.

Dong's research interests focus on understanding the molecular mechanisms of host-pathogen interactions using high-resolution approaches coupled to bioinformatics. He is interested in 'big data' analysis, where datasets generated from multiple omics platforms are integrated for system modelling.

Trained as an experimental biologist with hands-on mass spectrometer and bioinformatics skills, his work also contributes to the understanding of proteoforms, where splice variants and post translational modifications are experimentally and bioinformatically characterised followed by functional validations. The data generated also contribute to the next round of genome annotation as solid evidence of expression to improve gene model predictions.
